Manual vs. Auto Bias

In considering new directions in which to take the evolution of my system, I have run into conflicting claims as to which results in less distortion...auto or manual biasing, according to what product(s) the so called expert manufactures and/or represents...(Surprise!) How about some input from average consumers like myself who have had more experience with one or both?

Manual bias adjustments here with a 2 minute soft start (Lamm ML2.1).

Need a decent true RMS voltage meter (I use a Fluke) and one has to make adjustments to both plate voltage and current on each monoblock. The measuring jacks and adjustment pots are right on the top, with the required values written adjacent - very easy access. It's a ten minute job and the drift over time is small. It's not a problem.
